It’s more practical to have children younger. I have a 30, 24, and 23 year old. I’m 51. I recognize that my energy level has gone down some since I was in my 20s. I was able to go out and play hardcore football with my son as a bonding activity at age 40 when my son was 12 or 13. There’s nothing wrong with an older father as long as practical things are considered. Things like sports aren’t everything but it’s helpful for father and son to have some type of bonding activity. Can a 70 year old realistically do that?
